To all whom it may concern:

Be it known that 1, WILLIAM S. SEYMOUR, of Kenosha, in the State of Wisconsin, have invented certain new and useful Improvements.

in effecting the continuous feeding of both.

strands at the same speed.

To obviate this difficulty is the object of my improvement; and I attain the object by constructing and arranging the feed-rolls and guides so that the strands impinge upon each other and are grasped and pressed together as one wire at the point of their passage between the rolls.

The accompanying drawings illustrate the invention.

Figure 1 is a top view of that portion of a 1 machine of the class mentioned, which embodies the invention. Fig. 2 is a section of Fig. 1, taken on line as c. Fig. 3 is a horizontal section on line a: w of Fig. 2. Fig. 4 is a vertical section taken on line 3 y of Fig.2.

The frame A, boxing B, coiler 0, rolls D, and spring S, with plate 8 and set-screw s, for supporting and pressing the feed-rolls E Etogether, so as to hold the wire'with sufficient force to feed it forward but not flatten it, are all of the ordinary construction, and therefore are not described in detail.

The faces of the feed-rolls are provided with grooves e e, corresponding with each other in position on'the face of each roll, so as to be opposite to each other when the faces of the rolls are brought in line together. The depth of each groove is about half the. diameter of the wires a a,or a' little more, and the width is as nearly equal to the diameter of the wires as may be, so that when a wire is in the groove it will have as little vertical play as possible, and will project slightly beyond the face of the rolls.

Guides e,consisting of ways or grooves in bars e" c", which are separated by a plate resting in contact with their grooved faces,so that the grooves form openings at each side of the plate just'large enough for the wires to pass through, are placed in front of the rolls and arranged in a plane at right angles to their faces,or nearly so, and in line with one of the openings between the rolls formed by the grooves e therein. These guides direct the ,wires into the grooves e e, which are in line,

keeping them sufficiently separated, so that the rolls will have to deflect them slightly inward to cause their projecting sides to impinge upon each other atthe point a a. The wires are thus both pinched together as-one wire in passing between the rolls, both being grasped tightly at the one point of contact, so that neither of them can stop without the other. In this way the rolls, by means of their yielding pressure upon the wires, are adjusted a'u-' tomatically to the variations in the size of the wires and hold them the same, whether they increase or decrease in size, so that such variations have no effect upon the feed. After the wires have passed the pointof contact between the rolls similar guides or ways 6, formed in bars ei, separate them again and support them singly to the coiler.

The grooves e of the feed-rolls and the ways or guides are duplicated, so that one set may be used when the other is worn out by inverting the rolls and bars; but the duplication of these parts is not essential to the invention.

What is claimed is--'- The combination of feed-rolls E E, each having a corresponding groove, the two grooves meeting to form a single opening between the rolls at the point where their faces meet, and a guide having two openings or ways arranged in the plane of said opening between the rolls, so as to direct both of. said wires into the same, as specified.
